What is arteries and its function?
Arteries. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
Where are arteries?
Arteries are found in all parts of the body, except in the hairs, nails, epidermis, cartilages, and cornea. The larger trunks usually occupy the most protected situations; in the limbs, they run along the flexor surface, where they are less exposed to injury.
Why are arteries called arteries?
An artery (plural arteries) (from Greek ἀρτηρία (artēríā) ‘windpipe, artery’) is a blood vessel in humans, and most other animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.)….

What is arteries in anatomy and physiology?
artery, in human physiology, any of the vessels that, with one exception, carry oxygenated blood and nourishment from the heart to the tissues of the body. The exception, the pulmonary artery, carries oxygen-depleted blood to the lungs for oxygenation and removal of excess carbon dioxide (see pulmonary circulation).
How do arteries work?
The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
How many arteries are there?
However, there are more than 20 major arteries throughout the body, which then branch out into many, many smaller arterioles and capillaries. This extensive network carries blood to all parts of the body. Each artery is made up of three layers: a smooth layer on the inside.
What is the largest artery?
Aorta
Aorta Anatomy The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
Are arteries thick or thin?
Arteries carry blood away from the heart and veins return blood to the heart. Veins are generally larger in diameter, carry more blood volume and have thinner walls in proportion to their lumen. Arteries are smaller, have thicker walls in proportion to their lumen and carry blood under higher pressure than veins.
Why is an artery an organ?
Similarly, organs are defined are being a collection of tissues, which are joined in a structural unit to serve a common function.An artery is made up of several types of tissues including: Elastic tissue – this evens out the pressure changes in the vessel when the heart ventricles contract, by stretching and recoiling …
What are the two main types of arteries?
Types of Arteries. The carotid artery is a major artery of the head and neck. There are two carotid arteries, one on the left and one on the right. From their origins and for about half their length, the carotid arteries are known as common carotid arteries .
Which statement best describes arteries?
Answer: D) They have thick walls and transport blood away from the heart Explanation: Because arteries have to have thick walls for use of protection. Its when you get to veins where the walls get thinner.
What is the purpose of the arteries?
The function of the arteries is to carry oxygenated blood to organs and cells in the body. Because of this, arterial blood has a bright red color and flows away from the heart.
What are the main arteries in the human body?
Elastic arteries.
